$8.50 for the buffet (i think it's cheaper if you're a Pitt student). If you go in with low expectations you'll enjoy it. It's a good place for college students to pig out of greasy Chinese food. There's a pretty limited selection for a buffet, so if you're looking for something specific this might not be the place for you.
I think there were just two people running the whole place. One was cooking, the other was running the register, seating people and bussing tables after people left. I actually see this as a good thing, sometimes it annoying being interrupted every few minutes by the waiter asking if you need anything, or refilling a drink. I thought it was nice that they just leave everyone alone.
This was my first time there, but it sort of had a coffee shop feel in the sense that there were several people sitting alone studying. It was also very quiet compared to other restaurants.
